Bright yellow golf balls mysteriously appear, mutiply, and vanish in the performer’s hands. This is one of magic’s classic tricks and has been around for over 100 years. This set of balls are made out of a hard sponge-like material with a metal shell. This gives the ball and shell "cling feature" to keep them together until the magician pulls them apart with the thumb and first finger. In fact the ball/shell when nested together can even be tossed up into the air. This is a very nice set of the classic "Multiplying Billiard Balls" magic effect. Complete with instructions. 000FOL LF-0303
